I was working on a part and added a cut feature using the side of the part as the sketching plane. I went to create a second cut feature and the software would not select "any" face on the part to be a sketching plane (not the face I had just used which is the one I wanted, but I also tried to get it to select any face on the part and nothing would come up, and right click did not bring up a select other option either). I even tried to create a reference plane instead of a cut feature thinking it might let me use the face to create a plane and then I could select the plane in the model tree but it again wouldn't select any faces on the part.

I saved/closed the part and reopend it thinking that might help, but it still wouldn't select any faces. I had to exit the program, re-eneter (which had an error from a duplicate session since it hadn't correctly closed the program when I told it to so had to close and re-enter the program a second time) to get it to where it would work again and allow me to select a sektching plane.

Has anyone else run into this and have a fix? This time I only had two windows open, a small subassembly and one of it's parts so wasn't using a lot of memory and it was faily easy to close things out and re-enter the program. It would be much more of a PITA if it recurrs when I have my 1000+ part master assmembly and several nested subassemblies open which is a more usual condition.

It worked fine on the same surface literally 2 minutes earlier when I created the other feature so "shouldn't" be the video card or workload, in fat I had much less running on the system than I usually do and hadden't switch to or added any other tasks/program between the two attempts, only did a save-file..

I wasn't using the keyboard between the prior feature completion (entering the dimension numbers) and when it "stopped", but if you can tell me what key would turn a "select nothing" feature on I can try it to see what happens.

I had the same problem. I had to create planes on a surface to use it. I did what Alin said and pressed F5. I had edges only on and I had to turn on Surface. Icon right besides "Edge Only". left side about 4 or 5 over.
